DCM Z1: 040 Cataloging Source
LC/PCC catalogers should consult the PCC Post RDA Test Guidelines at: http://www.loc.gov/aba/pcc/rda/PCC%20Post%20RDA%20Test%20Guidelines.html for instructions on using RDA and/or AACR2 in new and existing authority records.
Subfield $b - Language of cataloging:
Add subfield $b "eng" when otherwise modifying NARs or SARs that do not contain this subfield.
Subfield $d -Modifying agency:
Add subfield $d [MARC 21 code] when modifying NARs or SARs unless your institution's is already the last MARC subfield $d in the 040 field.
Subfield $e - Description conventions:
When adding the subfield $e manually, add it after subfield $b and before $c. It is not necessary to move the subfield $e to this position if it is already present elsewhere in the NAR or if it is added by a macro or template. Use subfield $e "rda" in NARs and SARs when fixed field 008/10 (Descriptive cataloging rules) is set to "z" (Other).
